mapsound - Plots a sound map

### Calling Sequence

  `mapsound (w,dt,fmin,fmax,simpl,rate)`

### Parameters

- `dt,fmin,fmax,simpl,rate`: scalars. default values dt=0.1,fmin=100,fmax=1500,simpl=1,rate=22050;

### Description

Plots a sound map for a sound. It does FFT at time increments dt. `rate` is the sampling rate. `simpl` points are collected for speed reasons. `fmin` and `fmax` are used for graphic boundaries.

### Examples

    // At first we create 0.5 seconds of sound parameters.
    t=soundsec(0.5);
    // Then we generate the sound.
    s=sin(440*t)+sin(220*t)/2+sin(880*t)/2;
    [nr,nc]=size(t);
    s(nc/2:nc)=sin(330*t(nc/2:nc));
    mapsound(s);
